188 mg (426 μmol) of 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-[1-(trifluoromethyl)cyclopropyl]propanoic acid (racemate), 82.4 mg (426 μmol) of tert-butyl 4-aminobenzoate, 6.1 mg (43 μmol) of Oxima and 66 μl (0.43 mmol) of DIC in 4 ml of dimethylformamide were reacted according to General Method 5B. Following preparative HPLC [column: Chromatorex C18, 10 μm, 125 mm×30 mm, mobile phase: acetonitrile/0.1% formic acid gradient (0 to 3 min 10% acetonitrile, to 35 min 90% acetonitrile and a further 3 min 90% acetonitrile)], the title compound was obtained. Yield: 157 mg (59% of theory)
